REINFORCED-CONCRETE WALL AND LIKE STRUCTURE.

To all whom it may concern: I

Be it known that I, GEORGE WASHINGTON JACKSON,` a citizen of the United States, and

a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reinforced- Concrete Walls and Like Structures; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in reinforced concrete structures, as walls and the like, and refers more specifically to reinforcing mediums for such concrete structures.

The-invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

Among the objects of my invention is to provide a simple, inexpensive and strong reinforcing medium for concrete walls and like structures which may be applied at relatively small cost, and which may be of such character and arrangement that the reinforcing medium may be employed as means for tying together and spacing the form sides of the temporary supporting form during the erection of the wall, such tying and spacing members remaining in the body of the structure to constitute the reinforcing medium.

As shown in the a fragmentary, perspective view, partially broken. away, of a wall provided with reinforcing made in accordance with my invention. Fig. 2 is a horizontal .section thereof. Fig. 3 is a detail sectional view of one of the transverse reinforcing members showing the manner of arranging the flexible reinforcing members therein.V Fig. 4 illustrates a modification of the transverse reinforcing member.

The wall 10, shown in Figs. 1 and 2, may constitute the upright or vertical wall of a building. The reinforcing medium for said wall comprises a plurality of horizontally arranged, metal transverse members 11, 11 which extend through the wall from side to side thereof, and flexible wires or strands which are connected to and Vlaced between the said transverse members 11, 11 to constitute a net work which extends throughout and is embedded in the wall structure.

Specification of Letters Patent.

Application filed April 19, 1909.

Serial No. 490,689.

Thesaid transverse members and the flexible strands may conveniently constitute the spacing and tying members which, during the erection of the wall, were employed to connect together the sides of the temporary supporting form between which the wall was built and which supported the wall during the hardening of the wall material. Such an arrangement is shown in my coi-pending application for U. S. Letters Patent, filed of even date herewith, Serial Number 490,688. As shown in said co-pending application, the transverse members 11, l1 constitute spacing members which extend between and engage at their. ends the opposite sides of the temporary form structure, and the wires or strands constitute tying means which are laced through the spacing members and are connected with the sides of the form; and said wires are twisted or interlaced in the spaces between the form sides in a manner to bind the form sides upon the ends of the spacing members and thereby constitute a rigid form structure.

The transverse members 11 (constituting the spacing members of the form) are herein shown as made tubular, but may be otherwise made as illustrated in my said co-pending application. Said tubular reinforcing members 11 are provided near their longitudinal centers with transversely opposite openings 14, 14 and are provided at or near their ends with pins 15, 15 which extend transversely therethrough and beyond theV sides of said members. The wires or strands, which are laced through or upon the transverse reinforcing members and extend between and connect said members, may have the form of loops 16, 16, each occupying one end of each transverse member, with its closed end looped over the transverse pin 15. The ends 17, 17 of the looped wires may extend through the openings 14 and outwardly in opposite directions from the transverse members toward adjacent transverse members, and be interlaced with or twisted upon like wire or strand ends extending in a like manner from suoli other adjacent transverse members, as indicated at 18. 1

In the use of the wires or strands as tying means for supporting the temporary form illustrated in my aforesaid co-pending application, the closed portions'of the loops 16 extend to the outer side faces of the form sides to interlock with retaining deviceson said outer faces of the form sides, and when said retaining devices are removed and the form dismantled the extreme closed ends of t-he loops 16 may be twisted up against the transverse pins 15, as most clearly shown at 19 in Fig. 3, and thereby maintain the tension on said wires or strands to which they were subjected when they constituted the means for tying together the form sides. The closed ends of the loops 16, which may be twisted as shown, or otherwise disposed of, are turned backwardly into the tubular ends of the transverse members 11, and said tubular ends may, if desired, be closed by filling inthe same with the wall material, to present smooth, unbroken wall surfaces.

20, Q0 designate tension wires which are trained or looped over the outer ends of the transverse reinforcing members, outside the pins 15, and are interlocked with or twisted about the wire ends 17, 17 which extend between and connect adjacent transverse reinforcing members. As herein shown, the tension wires or strands are carried downwardly from upper transverse reinforcing members and are connected with the strands or wires 17 of lower transverse reinforcing members. rlhis arrangement of the tension wires provides a connection between upper and lower horizontal rows of the transverse reinforcing members and the wires or strands which directly connect the saine, thus producing a net work of reinforcing members which greatly adds to its reinforcing eliiciency to resist stresses impressed on the wall. The engagement of the looped portions of the tension wires with the pins 15, or other projecting parts of the transverse reinforcing members, holdsthe looped or intermediate portions of said tension wires fixed in proper relation to said members. The said reinforcing strands or wires 2O may extend continuously over a number of the transverse reinforcing members and be interlaced or wound upon the wires 17, or they may each be made of a length to loop over but one transverse member and to be connected at its ends with the wires 17 at each side of the reinforcing member about which it is trained or looped.

The wires or strands which are laced through or about the transverse members are herein shown as made of separate, relatively short lengths, each consisting of the looped portion 16 and the oppositely extended end portions 17. Said strands, however, may be made of longer lengths and laced through or about a plurality of the transverse members, with the same result of affording connections between the transverse reinforcing members. The transverse reinforcing members 11 may be roughened on their outer surfaces as indicated in Fig. 4 to increase the cohesive effect between said reinforcing members'and the material of the wall.

I claim as my invention :-v

the transverse reinforcing members at theirV central parts.

A reinforced concrete wall having embedded therein reinforcing means, comprising rigid reinforcing members extending transversely through the wall, iexible reinforcing strands having looped portions that extend along the reinforcing members from the center to the ends thereof, said strands extending between and connecting ther transverse reinforcing members at their central parts, and tension members looped or trained over the ends of the transverse members and laced about the strands which extend between and connect said transverse members.
